Report from Jutarnji newspaper, translated by Doctor "The Croatian Translation" Mitch from Sherdog:

Even though he is out of the ring 'cause of surgery and he won't be ready for a fight at least 30 more days, Cro Cop never had more options for fighting in his life.
5 MMA organisations (2 Japanese and 3 American) would like to see Cro Cop fighting for them. Cro Cop, for now, is leaning towards Dream, but he wants to go in the ring as soon as possible so all options are open.

Only thing certain for now is fight in Affliction – Dream co-promotion in Japan on 20th July. Mirko will be fighting Alistar Overeem, a fight that left many questions and now this guys are gonna answer them. Alistar was dominating the fight and then fight was stopped cause of the illegag nut shots by Overeem.

Other interesting fights on that card will be FYODOR EMELIANENKO vs. JEFF MONSON, and JOSH BARNETT vs. ANDREI ARLOVSKI could be interesting fight too.

"I'm looking forward to fighting against Overeem on 20th July, but I wan't to enter the ring as soon as possible. July is far away. In the next few days I will know more about my fights in 2009. I plan at least 4 fights from May 'till Deember, and I plan to fight 5 times in 2010." – said Mirko!

Note: These are very reputable newspapers in Croatia, but I couldn’t find any confirmation of this anywhere else. So maybe Cro Cop told them a few possibilities or plans and they wrote it like it was a sure thing.

It seems like the only sure thing here is that cro cop is fighting 20th July in Japan. The rest of the information you take “cum grano salis”

 UPDATE: 

Ok guys, here's the vid:

He is also looking to perform for Dream in May or for one of the american organisations in June because he wan't to get in the ring as soon as possible. No oponnents have been confirmed for now"

This news was also leaked a few months ago, stating that DREAM was planning an April announcement for a "special event" with an American organization, most likely Strikeforce and/or Affliction, pitting their fighters against theirs.  There was also speculation about a DREAM announcement regarding an Open Weight GP in the works.  It is unknown yet whether these announcements are related to the same event.  All we know now is that DREAM.10 is supposed to be taking place in July 20th.

DREAM SPECIAL EVENT

DREAM will announce details in April for a special event. The rumor is that DREAM will hold a tournament pitting its fighters against either UFC veterans or Strikeforce fighters.
